Measure the accurate GSM value of the product with the Presto GSM kit

Paper and its related products are widely used in almost every industry - from printing and publishing to packaging and design - the need for accurate testing has grown. Paper GSM (grams per square meter) testing is an important part of assessing the quality and suitability of the paper for its intended purpose. Testing the GSM value of paper and its related products is important to determine its quality. Thus, we at Presto have designed a high-quality lab testing instrument known as a Grammage checking kit.

This is one of the high-quality lab testing equipment that is used to test the grammage of different papers and their related products. In this blog article, we will explain what paper GSM testing entails, why it’s important, and how it can help ensure that you are selecting the most suitable paper for your needs. We will also discuss how the Presto GSM kit is useful in testing the quality of the paper. So, let us get started!

Why is GSM testing important and how to calculate the GSM value of the materials?

GSM is a unit of measurement for paper weight and stands for “grams per square meter”. The higher the GSM number, the heavier the paper. The main reason to test the GSM of a paper is to ensure that the paper and its related material will get tested for its quality. The thickness of the paper is a key to selecting its right quality, thus, it is important for the manufacturers to conduct the GSM value of the product with ease.

When the materials will be tested for GSM then the strength and quality of paper and its related products will be tested. The GSM or weight per unit area will be calculated by precisely cutting the testing specimen.

To calculate the GSM value of the product, one can easily make the use of GSM formula:

Grams per Square Meter = (Weight of Sample in Grams X 1000)/ Area of sample in cm2

With these features, you can easily test the GSM of testing instruments and ensure that quality products will be delivered to the customers. You can read more on the GSM checking for paper.

How Presto GSM kit will be helpful in testing the grammage of paper?

Presto has designed a high-quality grammage checking kit that can be used to test the grammage of paper and its related products. Besides the paper industry, this lab testing equipment can also measure the GSM value of different products like acrylic sheets, aluminum, and foils, bags and luggage of cotton, Paper, Printing, Packaging and leather, belts, foot ware, paper industry, package material, boxes, polyester & BOP films, thermal paper, Adhesive, and many more.

This easy-to-use lab testing instrument will make it easy for the manufacturers to conduct grammage of the product.

This grammage checking kit will be equipped with GSM weighing balance and a GSM round cutter. This high-quality lab testing instrument will test the grammage of the material accurately. Round Cutter for Grammage is provided with 4 built-in knives. By revolving the handle knob in a clockwise direction for a quarter of a turn, the cutter produces a circular sample of 100 cm². While the digital GSM balance is a highly accurate lab testing instrument that is used to test the weight and strength of materials for quality production.

Below we have listed the features and technical specifications of the grammage checking kit.
